United States Patent INCINERATOR WITH BAFFLE George V. Thompson, Albuquerque, N. Mex.

Application August 8, 1955, Serial No. 526,961

3 Claims. (Cl. 110-18) This invention generally relates to an incinerator, and more specifically provides an improvement on that structure illustrated and described in my copending application, Serial No. 321,915, filed November 21, 1952 now Patent No. 2,760,451, granted August 28, 1956.

An object of the present invention is to provide an incinerator incorporating smoke eliminating means therein so that the material being burned in the incinerator will be consumed without discharging excessive smoke from the incinerator. V

In carrying out the above object, a flexible conduit interconnects the smoke stack of the incinerator and the jacket adjacent the reticulated burner pot for increasing the temperature in the incinerator for assisting in the combustion of the material therein and further providing a baflle arrangement above the burner pot and associated with the smokestack so that the smoke is separated from the flame during the process of burning and the primary flame will be utilized as a secondary means of eliminating the smoke before it can reach the atmosphere thereby providing more complete combustion and less discharge of objectionable smoke to the atmosphere.

Other objects of the present invention reside in its simplicity of construction, efficiency in operation, adaptation for its particular purposes, and its relatively inexpensive manufacturing costs.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the incinerator of the present invention;

Figure 2 is a vertical, sectional view taken substantially upon a plane passing along section line 22 of Figure 1 illustrating the construction of the invention;

Figure 3 is a plan sectional view taken substantially upon a plane passing along section line 3-3 of Figure 2 illustrating the wire burner :pot construction together with the supporting rods therefor;

Figure 4 is a perspective view of the baflle element per se; and

Figure 5 is a detailed view illustrating the hinge connection between the base of the smokestack or the top of the jacket for limiting the pivotal movement thereof.

Referring now specifically to the drawings, the numeral generally designates the incinerator of the present invention which embodies in its construction a vertically elongated and substantially cylindrical jacket 12 having a plurality of air inlet openings 14 adjacent the body thereof and which may be provided with reinforcing ribs 16 extending circumferentially around the jacket 12. The jacket 12 may be provided with a bottom 18 and a rolled edge 20 at the upper end thereof which is open.

Extending transversely across the jacket 12 above the upper row of apertures 14 is a pair of supporting rods 22 "ice for supporting a reticulated wire basket or burner pot 24 for receiving the material to be burned. The burner pot 24 is in the form of a frusto-conical wire basket with an open upper end wherein the pot 24 is spaced from the jacket 12 for providing an area therebetween wherein this area or chamber is generally designated by the numeral 26 to permit air circulation around the burner pot 24 to facilitate combustion of the material positioned therein. The outer ends of the rods 22 may be provided with nuts 28 for securing the rods 22 to the jacket 12 for removal thereof when desired, although the burner pot 24 will be normally removed through the open upper end of the jacket 12.

A closure 30 is provided on the open upper end of the jacket 12 in the form of substantially a circular plate having a central upwardly bowed portion 32 having an inverted U-shaped handle 34 adjacent one side thereof. The other side of the closure plate 30 is provided with a hinge barrel 36 secured thereto by any suitable manner wherein the hinge barrel 36 surrounds a hinge pin 38 disposed between two mounting plates 40 secured to the outer upper edge of the jacket 12 in any suitable manner. The upper ends of the plates 40 project above the hinge .pin 38, as indicated by the numeral 42 for forming a stop for engaging the portion of the plate 30 adjacent the hinge barrel 36 for limiting the pivotal movement of the closure plate 30 to a position substantially as illustrated in Figure 2.

The center of the plate 30 is provided with an opening 44 and an upstanding cylindrical and tubular smokestack 46 is attached thereto in any suitable manner.

The smokestack 46 is provided with a tubular member 48 projecting through one side thereof and terminating in an upwardly and inwardly inclined edge 50. The outer end of the tubular member 48 is connected to a flexible conduit 52 which is connected at its other end to a right angular tubular member 54 extending into an opening 56 in the jacket 12 wherein a portion of the smoke and heated combustion products will pass through the tube 52 downwardly into the chamber 26 between the jacket 12 and the burner pot 24 for facilitating the combustion of the material within the burner pot 24. The flexibility of the conduit 52 permits the entire smokestack 46 and the closure plate 30 to be pivoted to an open position to permit access into the interior of the jacket 12 for plac ing material in the burner pot and removing residue therefrom. Inasmuch as the heated gases or air will be drawn from the smokestack 46 into the jacket 12, combustion will be more efliciently carried out wherein little smoke will be discharged from the smokestack 46.

To further assure complete combustion of the material in the burner pot 24, depending spaced flanges 58 are provided on the bell-shaped portion 32 ofthe plate 30, and these flanges 58 terminate in a downwardly and inwardly tapering fru-sto-coni-cal portion 60 which in turn terminates in an upwardly and inwardly tapering frustoconical portion 62 which forms a tunnel for a vertically disposed cylindrical portion 64 which extends into the lower end of the smokestack 46 in spaced relation thereto and terminates below the inclined end 50 of the tubular member 48. This construction generally forms a baffle so that the primary flame in the burner pot 24 will proceed through the cylindrical portion 64 and will be drawn into the tube 54 for assisting in the combustion of the material in the burner pot 24. Normally, the flame will be primarily disposed under the funnel portion 62 wherein the flame will be directed into the cylindrical portion 64 which will direct the flame towards the tube 48. The inclined end portion 50 of the tube 48 will assure that the hottest combustion gases will be drawn back into the jacket 12 to enhance the combustion of the material in the burner pot 24. The depending flange 58 is interrupted to provide passage for smoke which is normally disposed at the outer edges of the flame in the fire pot 24 wherein the smoke will progress upwardly through the smokestack 46 between the cylindrical portion 64 and the Smokestack 46 and will be drawn into the tube 48 along with the extremely hot gasesdischarged from the cylindrical portion 64. This baffle arrangement provides a more eficient and effective incinerator which will completely ignite and burn material in the fire pot without discharge of excessive smoke. In fact, very little, if any, smoke will be discharged under normal conditions.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and tie scribed, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
